CheckChecksum()

bool CheckChecksum	(	Span< const char > &	sp,
		bool	require_checksum,
		std::string &	error,
		std::string *	out_checksum = nullptr
	)

Check a descriptor checksum, and update desc to be the checksum-less part.

GetDescriptorChecksum()

std::string GetDescriptorChecksum

(

const std::string &

descriptor

)

Get the checksum for a descriptor.

• If it already has one, and it is correct, return the checksum in the input.
• If it already has one that is wrong, return "".
• If it does not already have one, return the checksum that would need to be added.

InferDescriptor()

std::unique_ptr< Descriptor > InferDescriptor	(	const CScript &	script,
		const SigningProvider &	provider
	)

Find a descriptor for the specified script, using information from provider where possible.

A non-ranged descriptor which only generates the specified script will be returned in all circumstances.

For public keys with key origin information, this information will be preserved in the returned descriptor.

• If all information for solving script is present in provider, a descriptor will be returned which is IsSolvable() and encapsulates said information.
• Failing that, if script corresponds to a known address type, an "addr()" descriptor will be returned (which is not IsSolvable()).
• Failing that, a "raw()" descriptor is returned.

Parse()

std::unique_ptr< Descriptor > Parse	(	const std::string &	descriptor,
		FlatSigningProvider &	out,
		std::string &	error,
		bool	require_checksum = false
	)

Parse a descriptor string.

Included private keys are put in out.

If the descriptor has a checksum, it must be valid. If require_checksum is set, the checksum is mandatory - otherwise it is optional.

If a parse error occurs, or the checksum is missing/invalid, or anything else is wrong, nullptr is returned.
